FILTERING REINFORCED CONCRETE RETAINING WALL Russian patent published in 1998 - IPC

FIELD: civil engineering. SUBSTANCE: filtering reinforced concrete retaining wall erected in seismic areas in water saturated soils has guard, foundation on one-row cast-in-place piles united by foundation mat, and drain. to increase reliability of construction, guard is made with face and filtering parts. Filtering part is provided with step to prevent soil creeping. Layer of slag from local boiler houses is used as filtering coating layer.
